Residents of Leeds, Washington County, were evacuated after a brush fire that began near exit 22 on I-15 spread. Officials said an outbuilding was destroyed and several structures were threatened.

LEEDS, Washington County — A wildfire burning outside St. George that forced the evacuation of about 60 homes was estimated to be 90 percent contained Sunday afternoon.

The Quail Fire has burned more than 1,700 acres south of Leeds and north of Harrisburg. For a while Saturday, the fire was blowing heavy smoke across I-15.

Utility crews were working Sunday afternoon to replace power poles in the area damaged by fire, according to Mike Melton, fire management officer for the Utah Division of Forestry, Fire & State Lands.

Aggressive air strikes were believed to have saved many homes in the area, according to fire officials. Two "low-value" sheds were destroyed in the fire, fire officials said. No other structures were threatened Sunday.

One firefighter was treated Saturday at a local hospital for a "heat related illness," according to fire officials. No injuries were reported Sunday.

The fire started about 2:50 p.m. Saturday. The evacuation order was lifted Saturday evening.

Fire information officer Nick Howell said the fire was started by a man who was burning cheat grass on BLM land.

The man could be charged with reckless burning or causing chaos, he said.

About 80 personnel were assigned to the fire, as well as three helicopters and nine fire engines. Three engines are expected to patrol and continue mop-up work Monday.
